Accreditation of stable isotope ratios methods: guidelines to implement a quality system according to ISO/IEC 17025:1999
Abstract
Several types of isotopic analysis, carried out using SNIF-<sup>2</sup>H-NMR and/or IRMS, are now standards or validated methods for testing the authenticity of food products. This study will offer guidelines on implementing a quality system for the accreditation of methods for stable isotope ratio analysis, based on ISO standard 17025. The focus will be on determining repeatability, linearity and uncertainty. Moreover, issues related to accuracy, reference materials, proficiency tests and some unclear areas of official standards will be tackled, and suggestions to improve the effectiveness of this analysis will be provided.
